Product Description
Author: Clifford Hicks. 168 pg. PB
Alvin’s “sixth sense,” which clearly indicates that a crumpled note holds an unmistakably coded message, is about to catapult two seventh grade secret-agents-turned-cryptographers (plus Alvin’s younger sister Daphne,“the Pest”) into the intricacies of authentic code detection and the dangers of a newly stirred-up 100-year-old mystery. Even Alvin’s “Magnificent Brain” is nearly put on overload before the bang-up solution to the code and the mystery carry the three agents to an ending that is satisfying to all…well, to almost all. This reprint of a classic favorite includes Alvin’s own notes on cryptography in an appendix at the back. Ages 10+
